Referring more in detail to-the parts: 1' 90. Inaccomplishing these ohjectslhave prodesignates a motor of any suitable type, vidoda carbureter comprising a measuring comprising a plurality of cylinders 2, de\ri ce ivhich operable; from the crank mounted on a crank case 3 and having an "shaft of the motor with which the ca'rli uintake manifold 4t and exhaust manifold 5.

The measuring device comprises a casing 10, suitably mounted on the crank-case 3 of the motor, and inclosing a chamber 11 for containing driving mechanism. for operating the measuringelenients, which latter are contained'within a chamber 12 in'theis secured to the casing 10,,

With a disk 20 which is held yieldingly against the inner face of the chamber 12 by 1 a spring 21, and which is provided with a plurality of diagonally disposed pockets 22' in its outer face.

The body of the spring 21 is located in a groove 21 inthe outer face of the casing 10, and a spring 16',- 1

cated in a similar and adjacent groove engages the stufling box to yieldingly hold'the latter in place "travel past a cupped portion 2301 the cham- 'ber 12, so that l-iquid'fuel' contained therein may enter the pockets 22, and "for travel past and invclose contact with'the aised I portion 24, so that fuel the pockets and carried to an outlet port 25, located at about the center ofthe raised portion.

25 Integral with the head 13 is a boss26,

having a tube 27 threaded thereinto and communicating at its inner end with the- I outlet port 25, and at its outer end with the heater 6. The boss 26 also comprises an 30' upwardly opening cup 28, having a port 29,

ycess 32 in the upper portion', of the chamber,

45 and which extends upwardly toa point .above the level of the supply tanks 34 --(I .ig.I) 4

The 'presen't device'is' particularly adaptmed'for receiving two kinds ofjliquid fuel convenientpoint, and con} i' ducted' t'o a'valie -38 on the head 12 by tubes 'and 36. The valve 38 preferably comprises a seat 39, which is integral with the 5!? head 13, and contains a valve plug 40, having ba-11:": and socket connection 41' with a frod42 which extends to inconvenient point of control'and is provide'd. at its free end,

with a handle 43. n'lhe valivm plug is profigi v-ided with aninety degree slot 44, which is adapted for simultaneous pommunication avithfia port45'rtleadingato the measuring chamber,-and with eltner. one of the confi duits' 46 01-47 thatcommunicafe with-the 06 .fuel supply tubes 35- 36 respectively, so

The disk 20 is adapted. for

maybe trapped in openings 25,29, in .'order that the fluid may be drawn by the the feeding disk ing block 71 which is,

that liquid fuel from either, of the tanks 34; may flow separately into the measuring chamber. 4

If theengine. has, been operating on the fuel from one of the supply tanks and it is desired to change an use fuel from the other tank, which ma kind or grade, it is necessary to drain the measuring. chamber before the new fuel is introduced. In'accomplishing this function, I have provided the valve plug 40 with a longitudinal slot l8 (Fig. VII1)-, which is adapted for communication. with an aperture 49 in the head 13 and with a notch 50 in the base of the valve seat 39, when the slot 44 is out of communication with both of the'feeding conduits, so that when theconduitsA-G and l7 are closed, the port 49 .is open, to drainthe measuring chamber.

Thegvalve plug v40 is also provided with lock nuts 51 and a spring washer 52 for holding it snugly to its seat while allowing free revoluhle movement to its various-positions.

,Near the upper portion of thehead 13 isa priming device ,coinprising'a needle valve 5-L which is held to its seat by means of a coil Y be of a different sarin 55 and asses throu h; a retainin nut 56. The needle valve is provided with a finger grip 57 and is adapted to normally close a port 58 in the measuring chamber 12, so that the liquid fuel will not flow therethrough, and through an aperture 59 which communicates with the'cup 28 unlessthe valve 5% is opened, in which case the cup 28 will fill with the liquid fuel andfiow through the port 29and into the discharge conduit to deliver a greater quantity of fuel to thegengine cylinders, and hence a richer mixture at "the start. I i 1 The actuating mechanismf for revolving 20 comprises a ratchet wheel 61 rigidly and within the chamber '11. Revolubly mounted on the hub 62 ofthe ratchet wheel 61 and in an aperture 63 in the cover 64' of the chamber 11, is a hub 65, having a slotted shank 66 and having diametricallv extende'xtr'emity of each ofthe arms 67 is a pawl 68, which is held yieldingly in engagement.

Revolubly mounted in the block 71 is a shaft 72. having a socket 73 into which the slotted shank 66 is projected; the end of the shank having a transverse slot 66" in itfsend adapted for receiving a pin 74, that extends across the socket, so that the shank reporta motor worm I :(37 are t loseil" 1" the interval in which the pawl are iii.en-

When the motor has started and is running on its. own power, the worm 77 on'the cam shaft 7 8 imparts revoluble movement to the 5. worm gear 76 and arms 67 on which the pawls,68' are mounted, so, as to carry the latter over the peripheral face of the ratchet wheel 61 and over the cams 81 and 82, so that the pawls \vill alternately engage the 10' ratchet wheel and turn it through an arc, the length of which is determined by'the position of the cams, the effective-position of the'cams being dependent on the temperature and pressurewithin the regulator 89, which varies with the temperature and pressureof the surrounding atmosphere and with the absolute pressure in the intake man ifold and, in the initial condition of the motor, holds-the camsso thatthe ratchet pawls impart a very slight movement to the ratchet wheel. The measuring disk being operatively connected. with the ratchet wheel, is carried therewith, and the pockets 22 are filled with gasolene as they pass the cupped portion 23 of the head 13, and the gasolene is trapped in said pockets as the disk moves over the raised portion 24 and is carried upwardly to the ports 25-29.

The operation of the'motor causes a par; tial vacuum to be formed in the intake manifold, which is communicated to the port 25 through the tube 27, so that the fluid isremoved from the pockets and displaced with air which enters through theport 29. liuction from the intake manifold draws the liquid fuel through the tube 27 into the heater 6, where it is vaporized by exhaust ing gases and delivered into -a tube 99in the form of vapor. This vapor is then delivair from the valve 104, to form proper fuel mixture, which is delivered into the engine cylinder through the screen 109 and valves 108. Under such conditions and with the throttle open; the absolute pressure in the intake manifold increases and the diaphragm will contract, thereby moving the cam 82 more nearly into alinement with the 'cam 81, and permitting thepawls a longer contact with the ratchet wheel, and consequently a greater number of revolutions of the measuring disk, giving an increasedsupply of fgasolene to the cylinders. As 50011 as the motor, has become well heated, the 55 handle 43 is manipulated to .close the gasolene port leading from the kerosene supply tank, in' which position the parts operate as just described, but with kerosene instead of gasolenelas thefuel fluid, I a

When the motor; is to be started, after having run onkerosene, the measuring chamber may be drained "of the heavier liquid before the'z'gasolene is turned in, by turning the valve until the groove 48 5 registers with the aperture 49, in which po- 'cumference. both supply conduits will be the priming valve 54, which uring chain mg mechanism comprising a disk, having concentrically with said-disk and ratchet shaft, pawls ered into the chamber 101 and mixed with 'ed in said adapted for with said disk, pawl arms and and adapted for operative enga ithe ratchet wheel, and a cam fored in said sition of the valve the liquid fuel will flow through the notch 50 until the chamber is empty, it being apparent that as the groove lies in thethird quarter of the valves circlosed during the' drainingoperation It is'sometimes. necessary, during cold weather, to furnish a richer mixture to the cylinders for starting the engine,'and in ac- 'complishing this function I have'provided may beactuated v d to permit lizguid fuel to flow from the measor into the opening 28 from which it is drawn by suction into the motor.
